Novel low dimensional quantum phenomena at (110) LaAlO3/SrTiO3 (LAO/STO) interfaces are expected after the quasi two electron gas similar to that of (001) LAO/STO was found this system. Here, we report superconductivity with a superconducting transition temperature ≅ 184 mK interfaces. The characteristics consistent our analysis based on Berezinskii-Kosterlitz-Thouless transition. estimated layer thickness is about 18 nm. This discovery may inspire new studies and open additional...
Abstract Polycyclic multiple resonance (MR) molecules reveal narrowband emission, making them very promising emitters for high color purity display. Nevertheless, they still have challenges such as aggregation‐induced emission quenching and spectral broadening. Overcoming these obstacles requires an in‐depth understanding of the correlations among alterations in their geometries, packing structures, molecular vibrations corresponding changes photoluminescence (PL) properties. Herein, it is...
The integration of mechanical flexibility with stimuli‐responsive optical properties in organic single crystals (OSCs) remains a formidable challenge due to the intrinsic rigidity π‐conjugated systems. Herein, we report rationally designed OSC, FBCF, that synergistically combines elastic deformability, broad piezochromism and low‐loss waveguiding via planar benzothiadiazole (BTA) core fluoroarene termini. molecular architecture enforces face‐to‐face slip‐stacking multiple noncovalent...
Experimentally, we found the percentage of low valence cations, ionization energy cations in film, and band gap substrates to be decisive for formation two-dimensional electron gas at interface amorphous/crystalline oxide (a-2DEG). Considering these findings, inferred that charge transfer from film should main mechanism a-2DEG formation. This is induced by oxygen defects can eliminated electron-absorbing process film. Based on this, propose a simple dipole model successfully explains origin...
The out-of-plane magnetoresistance of a $\mathrm{LaAl}{\mathrm{O}}_{3}$/$\mathrm{SrTi}{\mathrm{O}}_{3}$ interface is commonly positive due to significant orbital effect. In this paper, large negative observed at $\mathrm{LaAl}{\mathrm{O}}_{3}$ and Fe-doped $\mathrm{SrTi}{\mathrm{O}}_{3}$ upon the application an magnetic field. Such attributed enhanced two-dimensional weak localization Kondo We think that these two effects are mainly consequences intentional Fe dopants in substrate, which...
Using non-equilibrium molecular dynamics simulations, we investigate the thermal conductivity variation of graphene with different hydrogen doping coverage and orientation. It shows that decreases increasing coverage. The decreasing rate, however, depends on Based kinetic theory lattice transport, study effect orientation phonon density states, dispersion relation, relaxation time, specific heat. While has little heat, it group velocity increases phonon-phonon scattering in graphene....
The interfacial atomic arrangement, which is different from that in the bulk form of heterojunction, can induce a reconstruction electrostatic field at interface. For conventional semiconductor heterointerfaces, it known such results band bending, creating quantum well two-dimensional electron gas (2DEG) formed. In this article, we show mechanism still works multivalent oxide heterojunction: for...
By comparing the in-plane and out-of-plane orbitally dependent magnetoresistance under a magnetic field of 9 T, conductive layer thickness ${\mathrm{LaAlO}}_{3}$/${\mathrm{SrTiO}}_{3}$ interface is determined for temperatures between 45 300 K. As influence spin-orbit coupling cannot be ignored when considering dependence at below K, lower employed. The results show that increases gradually then remains constant as temperature decreases. Such tendency well reproduced theoretically by...
Carrier density $({n}_{\mathrm{s}})$ is a crucial parameter that governs the properties of correlated oxides, so field-effect approach an ideal tool to investigate novel physics system. Here, carrier-mediated transport slightly doped anatase ${\mathrm{TiO}}_{2}$ epitaxial films were studied by electric double layer transistor (EDLT) gating. The ${n}_{\mathrm{s}}$ has been increased hugely, and concomitantly, channels undergo insulator-metal transition with decrease in resistivity almost...
Flexoelectricity has been proven to be an effective way in tailoring a material's properties. Here, we report the flexoelectricity-induced transport modulation two-dimensional electron gas at (110) LaAlO3/SrTiO3 systems. Under different strain gradients induced by mechanical bending, interfacial resistance changes according flexoelectric field directions. By measuring electrical properties of interface under variant states, demonstrate that effect is affected oxygen partial pressure during...
Abstract Organic luminophores exhibiting both fluorescence and phosphorescence at room temperature are attractive but rare, due to the limited design strategies of (RTP) molecules. Here, construction electron donor‐acceptor‐donor (D−A−D) structure, which can afford multiple powerful intermolecular interactions electronic communications, is proposed as an effective method achieve RTP. Two compounds NBCM PBCM were designed with different withdrawing groups. Both exhibit efficient RTP long...
